In the last few years, technological advancement has led to the use of wearable body sensors for gathering patient information. Wireless body area networks played an essential role in the modern medical era. Through wearable body sensors, patient data are sent to medical professionals in real-time without any hindrance. This information moves through the public channel, and thus proper security and protection are needed because of its sensitiveness. Many authentication protocols proposed for solving these issues were neither secure nor cost-effective. This paper proposed an authentication protocol using certificateless cryptography for wireless body area networks to resolve the associated security concerns. A formal security analysis is done using the Burrows–Abadi–Needham logic shows that the proposed protocol is resilient against prevailing attacks. Additionally, we employ the Real-or-Random model for mathematical proof and Automated Verification Security Protocol and Analysis simulation tool for security analysis. A detailed comprehensive comparison with the existing protocols indicates that the proposed protocol is cost-effective with improved functionality.
The vehicles are connected through the internet in the vehicular Adhoc network environment. When any emergency vehicle like an ambulance arrives, we have to create a green corridor to that ambulance so that it will reach safely. The communication between the ambulance and the other entity like RSU or other vehicles through the open channel, These open channels are the main target by the adversary to get the messages which will transfer between two entities. The adversary will modify, delete or eavesdrop on the message to do the attacks like privileged-insider attack, replay attack, man in the middle attack or other related attacks. In this paper, we will propose the new TCPPA authentication protocol to secure the intelligent transportation system in a vehicular network. We also analyzed the security features in informal security analysis. A formal security analysis is done using the BAN logic. Additionally, we employ the ROR model for mathematical proof and the AVISPA simulation tool for security analysis. At last, an exhaustive comparative analysis will be conducted between the proposed work with some other existing works.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
